Vietnamese shrimp producers can ignite exports using Genics technology – VietShrimp 2024

By Dirk Kruger 

After a disappointing 2023 season, Vietnamese shrimp producers are planning for a year of growth in 2024, and Genics is committed to being part of the industry’s recovery & expansion. 

Last week, I visited the 2024 VietShrimp Aquaculture conference in Ca Mau as part of the Australia–Vietnam partnership for Climate-Smart Agriculture delegation to find out what’s on Vietnamese shrimp producers’ minds and how Genics can help them achieve their goals.

Vietnam’s new initiatives in shrimp export markets 

VietShrimp is co-hosted by the Vietnam Fisheries Society (VINAFIS). Talking about the importance of Vietnam’s shrimp industry, VINAFIS Chairman Nguyen Viet Thang said that shrimp is a vital export for his country, delivering nearly US$4 billion to the economy each year. But in 2023, the sector saw an export slump of nearly 20%, caused by rapid modernization by South American and Indian producers. This hardship has prompted Vietnamese industry thought leaders to refocus on their own pathways to expansion through quality assurance and biosecurity credibility. 

In line with their export resurgence goals, the VietShrimp organizers designated the key themes of this year’s conference as technological development, sustainable production, quality assurance, and farming efficiency.   

Vietnam’s shrimp farmers are targeting US$4.3 billion in exports for 2024, a goal dependent on recapturing US and Chinese customers who make up 45% of export value. Return to form in these export markets hinges on taking a competitive stance on biosecurity and quality control, which are high priorities for foreign buyers.  

Speaking at the conference, Deputy Minister of Agriculture and Rural Development Phùng Đức Tiến emphasized that Vietnam’s shrimp industry must integrate smoothly with the world economy in coming years. 

“We believe that VietShrimp 2024 will be a bridge between the business community, partners, and customers,” the Deputy Minister said. “It’s a forum for the shrimp industry to connect with the world, with learning experiences and techniques of advanced countries to upgrade the Vietnamese shrimp industry in the future.”

As I talked to farmers and industry leaders at VietShrimp, it confirmed that the pain points for Vietnamese shrimp producers are closely tied to technology adoption.  

The farmers I talked to are looking for ways to enhance efficiency by optimizing breeding programs for better yield. They also need reliable disease testing technology for very early pathogen detection to prevent catastrophic stock losses from pathogens.  

I had a lot of positive interactions with shrimp producers who could see the connection between Genics technology and the need to implement reliable strategies for product improvement. Genics Comprehensive Shrimp Solutions Suite can support sustainable growth for Vietnam’s farmers, as it has in other parts of Asia and Latin America. 

Genics has export growth solutions for Vietnamese shrimp producers  

Genics has already demonstrated its value as a breeding and biosecurity partner for shrimp producers in Australia, South America, and Indonesia.  

Indonesia’s shrimp industry has many legitimate points of comparison with its Vietnamese counterpart. Both industries are in steep technology adoption phases, and both countries’ producers want to expand their domestic potential onto the world stage. 

Talking with us this year, Henry Wijaya, the chairman of Indonesian shrimp producer Prima Larvae Bali, said that Genics services have proven to be a valuable investment for his company.  

“We have peace of mind, knowing that Genics is an accredited pathogen detection lab. We can also say to our customers that we have external pathogen verification by an internationally recognized provider with a great reputation,” Henry said in a recent case study interview. 

That sentiment aligns with the aspirations of Vietnamese producers right now. In an increasingly competitive export market, Vietnam’s farmers need to deliver shrimp that meet the highest quality standards and are certified disease-free by reliable testing methodologies

Genics industry-leading genetic profiling, digital phenotyping, and pathogen detection technology can give Vietnamese farmers the competitive edge they need. US and Chinese importers are looking for quality assurance standards linked to reliable, state-of-the-art technology, and Genics shrimp services meet that expectation. 

I made many new connections with local producers at VietShrimp and I’m looking forward to helping them get the full export advantages of Genics partnership.

Research shows POC tests only detect high-level infection of WSSV – but there’s a better solution for shrimp farmers   

In 2019, Australia’s CSIRO undertook a scientific investigation into the effectiveness of shrimp point of care test kits in detecting white spot syndrome virus (WSSV). At the time of the study, point of care tests had become a go-to method of disease detection for farmers, a situation that persists to this day. But, with the CSIRO’s recent presentation of their findings at ProAqua Symposium, it’s time for an urgent reassessment of testing practices.   

(Image above: the author, Dr. Melony Sellars, working in the laboratory.) 

White spot virus demands best practice controls   

WSSV continues to persist as one of the global shrimp industry’s most economically impactful pathogens. In 2016, severe outbreaks of WSSV in Queensland, Australia, snapped WSSV to the forefront of the national shrimp industry’s attention. With the WSSV emergency response destroying farm populations and costing producers millions of dollars, farmers urgently needed a way to monitor their animals for early-stage WSSV infection.   

Global uptake of POC test kits, including for WSSV, had become second nature in the shrimp industry, being used for various purposes, including early-stage WSSV detection. With WSSV devastation at their doorstep in 2016, the Australian Industry requested access to such kits, which first required Government approval.    

In 2019, at the request of a battered shrimp industry, the CSIRO commenced a laboratory-based evaluation of WSSV tests to determine the efficacy and fitness for purpose of POC test kits compared to laboratory PCR Testing.   

CSIRO examines WSSV POC testing   

Commencing in 2019, Australia’s Commonwealth Scientific and Industrial Research Organisation (CSIRO) collaborated with shrimp industry stakeholders on a comprehensive study of WSSV testing methods. The study report – Evaluation of point of care (POC) tests for White Spot Syndrome Virus (WSSV) – compares commercially available tests designed to detect WSSV on commercial shrimp farms with laboratory-run PCR WSSV tests.  

The CSIRO’s research compares and assesses five WSSV tests, comprising three rapid antigen-style and two PCR-based tests. After exhaustive testing, the study clearly shows that rapid antigen POC test kits yield inferior limits of detection when compared with PCR laboratory testing. The research group found that rapid antigen-style POC tests were a sub-optimal defense against WSSV because “POC tests had lower sensitivity than validated laboratory reference WSSV qPCR tests.”   

The lack of sensitivity of rapid antigen POC testing is such that it actually creates a false sense of security for farmers. The CSIRO study’s findings are crucially significant for the global industry because the current expectation among farmers is that POC tests can detect WSSV in the early stages of infection, providing early warning of disease. However, CSIRO’s study identifies vital issues with rapid antigen POC testing kits, which means that they are not, in fact, a solution for WSSV early warning and prevention.   

The dangerous flaw revealed by CSIRO’s POC testing study   

CSIRO’s study reveals substantial issues with POC test kits as a means to prevent WSSV outbreaks. Among the problems with POC kits, CSIRO emphasizes the gap between user expectations and actual test kit sensitivity in the field.    

Farmer’s confidence in POC test kits is supported by the perception that they can detect WSSV early enough to prevent large-scale stock losses. However, CSIRO’s research reveals that the studies used to prove POC kit capability were conducted in laboratory conditions, where the infection speed and transmission pathways did not reflect the reality on farms. A careful reading of manufacturers’ guidelines on some kits also reveals that validation occurs on synthetic templates, providing unrealistic guidelines for real-world use on shrimp samples.  

The CSIRO team writes in the report that “in existing literature, all POC tests were reported to be able to detect WSSV in the early stages of infection.” However, they continue, “the live prawn experiments conducted in this study demonstrate that white spot disease progresses much faster when prawns are injected with WSSV compared to when they are cohabitated with WSSV infected cohorts. Thus, the predicted timeframe from WSSV exposure to WSSV detection by POC testing in the field may be over-estimated…”    

(Image above: shrimp infected with WSSV.)

This finding underlines the crucial problem with POC tests as a means of WSSV control. The virus develops more rapidly in shrimp that are deliberately infected for the purposes of POC test kit validation. However, when used in commercial settings, where disease develops more slowly in individual animals, POC test kits fail to find the virus early enough to prevent infection from spreading throughout farm populations. This fatal flaw in POC kit sensitivity means that if farmers continue to use them for WSSV detection, they will miss the virus in its early stages, leading to continued disease outbreaks.       

Protecting against WSSV requires a strategic change   

WSSV is now endemic worldwide, so vigilant preventative monitoring with fit-for-purpose testing technology is essential. WSSV can destroy entire shrimp farm populations in mere days, underlining the need for an effective early detection regime.     

One of the key findings of CSIRO’s recent study is that when it comes to reliable testing for WSSV, current POC test kits cannot match the sensitivity and accuracy of validated laboratory-based PCR testing.     

“For all 3 WSSV strains assessed, the laboratory reference qPCRs were 10-fold more sensitive than the most sensitive POC test,” the CSIRO study found. Indeed, PCR tests are 100-fold more sensitive than one of the most commonly used POC test kits on the market. CSIRO states in their findings that for “For weak positive samples,” – typical of early stage WSSV infection – sensitivity of POC tests is inadequate, “with only 56% – 78% of replicate weak positive samples testing positive, in contrast to the 100% concordance demonstrated by the laboratory reference qPCRs.”    

(Image above: laboratory pathogen testing for WSSV is more accurate and reliable than conventional POC kits.) 

For farmers, the conclusion to be drawn from CSIRO’s research is emphatically clear: to avoid destructive outbreaks of WSSV, the shrimp industry urgently needs to pivot toward using lab-based PCR tests for routine testing instead of relying on rapid antigen POC kits. Notably, such lab-based PCR tests must also be properly validated by the laboratory personnel, with all assays varying in performance based on equipment, chemistry, people, and operating conditions.   

With turnaround times on laboratory testing as short as twenty-four hours, any concerns about immediacy can be set aside. Performing a POC test on-site gives the false security of quick results, but the reality is that due to their lack of sensitivity, POC tests miss disease in its early stages when a lab test would detect it.    

The research takeaways for farmers  

The CSIRO report clearly shows that lab-based PCR tests are more sensitive and reliable than the currently ubiquitous POC kits. It should also be noted that such lab-based PCR tests must be properly validated in any given laboratory to ensure optimal performance and that validation is an ongoing requirement, not a one-off event.  

The early warning aspect of lab-based PCR testing delivers a vital advantage to farmers since knowing about WSSV infection on their farm a few days early can prevent catastrophic stock losses.     

When disease outbreaks can decimate shrimp farms in mere days, and millions of dollars are on the line, CSIRO’s research sends a strong signal to the shrimp industry to stop relying on POC kits. Lab-based PCR testing, with its superior sensitivity and reliability, is the only way to effectively manage the threat of WSSV.
